Yeah, exactly. My girlfriend did it too, using information theory. In my solution, I did chose a word that minimized the size of the larger set of possible guesses. It's not strictly information theory, but it's a good approximation of finding 'the word that brings the most information [this turn]'.

I suspect that this researchers work involves formalizing and proving the optimality of their solution.
